COMBINED LAMP AND SIGNAL POST.

SPECIFICATION forming part of Letters Patent No. 361,901, dated April 26, 1887.

' Application filed November 27, 1886. Serial No. 220,085. (No modelf I To all whom it may concern.-

Be it known that I, JOHN ELLIOT SMITH, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in a Combined Lamp and Signal Post; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a combined lamp and signal post; and it consists in the construction, arrangement, and combination of the several parts, substantially aswill bchereinafter described and claimed.

In the annexed drawings, illustrating my invention, Figure 1 is an elevation of a lamppost and signal-box combined. Fig. 2 is a vertical section through the same, and shows the mode of carrying underground wires into the signal-box. Fig. 3 is a rear elevation of the signal-box frame and a portion of the post.

Fig. 4 is a horizontal sectional plan on line a: of Fig. 3. Fig. 5 is an elevation similar to Fig. 1, with a modified form of signal-box. Fig. 6 is a vertical section transversely through the same. Fig. 7 is a rear elevation thereof. Fig. 8 is a sectional plan 011 line g y of Fig. 7. Fig. 9 is a View showing a post divided in two parts and an interposed frame connecting the two parts and supporting a box containing signaling apparatus, and showing also the mode of connecting air-lines to the post, so that they maybe carried into the signal-box. Fig. 10 is a vertical section through a portion of the same.- Figs. 11, 12, 13, 14, and represent certain details of construction.

Like letters denote like parts throughout the several views.

A represents the tubular trunk or post of an ordinary gas burning or electric lamp, which post incloses the gas-supply pipe or electric conductors, and carries at its upper extremity the lamp 0, and is provided just below the lamp with the ordinary cross-head or frame, B, and in the base of the post an opening with door for access to the wires connecting earth-circuits, as hereinafter explained.

In order to combine with the lamp-post as usually constructed an alarm or signaling apparatus, I provide a frame, D, (see Fig. 15,)

'boX containing the signaling apparatus.

which is designed to connect the upper and lower portions of the post and support the This frame D may be of any suitable shape and size. It may be rectangular, square, oval, or irregular, as desired, and may have any exterior configuration, ornamental or otherwise. As shown in the drawings, the top and bottom portions of the frame D appear to be preferably curved. Said top and bottom portions are provided centrally with circular openings, and the mode of attaching the frame to the post A is as follows: The post A as it stands is severed at a convenient point, by cutting or otherwise, into two portions. The frame D is then interposed between these two portions by inserting their ends into the top and bottom openings of the frame and securing them therein.

In order to complete the frame, and as a method for continuing thegas-supplypipesand electric conductors from the lower section of the post to the upper section and the proper supporting of the signaling-box within the frame, I provide a vertical rib, b, which is adapted to receive the gas-supply pipe a or conductors, for it will be noted that when the lamp-post is cut in half the inclosed gas-supply pipe must likewise be divided. I therefore find it convenient to provide each end of the pipe portions with a knee or elbow, 0, whereby I am enabled to connect the ends of the pipe by a connecting-tube which shall be located at some distance out of a perpendicular line between said ends, and thus out of the way of the signaling mechanism,which may be placed within the frame, and the hollow rib b is provided to receive this connecting-pipe and for the electrical conductors; This rib b may be cast with frame D, though I find it convenient to make it as a separate piece, to be attached to the frame after the gas-pipe has been arranged therein in the manner already set forth. The rib b may be cast as a pipe, (instead of with the recess,) into which the two sections of the supply-pipe can be inserted, and thus form the channel for the gas between the two sections of pipe. (See Fig. 6.)

When underground wires are used, the base of the post is provided with an opening, d, to facilitate the connection of the wires between the instruments and the earth-circuits. \Vhen air-lines are to be connected with the instruments in the signal-box, a suitable frame, as G, is mounted on the top of the post, near the burner, and the wires carried down therefrom through the post to the box. This insulating attachment consists of metal tubes sufficient in size to receive the connecting-wires, which are first fastened to suitable insulators, G, which have a wide mouth forming the upper endsof the tubes, and the tubes, being fastened to the lamp-frame, are carried into the column of the post to such distance as may be desired. The wires, being carried through the tubes whose mouths open downward, are thus protected from dampness.

Within the box-frame the instruments are arranged as desired, H representing in Fig. 2 one style of box and I in Fig. 6 denoting a different arrangement of the supporting-frame, it being evident that the frame, the box, and the arrangement of instruments or wires may be varied at pleasure as long as the essential features of my invention are not departed from. Further, it is evident that the signal-box frame may be cast integral with the post, as in Figs. 1 and 5. This can easily be done when both post and frame are to be newly constructed; but when my invention is to be applied to old posts that have been and are now in use, the mode of interposing the box between the several portions of the post may be resorted to, as in Fig. 9.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is- 1. The combination of the several portions of the post of alamp, the signal-box frame interposed between said portionsand having a rear plate provided with a hollow rib, and the gas-supply pipe or conductors, so arranged that the portion within the signal-box frame may lie in the hollow rib, substantially as described.

2. The combination of the post A, having a lower opening, (I, the frame D, having door E and rear plate, F, provided with rib Z), and the inclosed gassupply pipe a, or conductors, all arranged substantially as set forth.

3. The combination of the post A, carrying lamp 0, the signal-box framehaving the ribbed rear plate, the gas-supply pipe at or electrical conductors, arranged as set forth, and the frame G, mounted upon the post or lampframe, substantially as shown and described.

4. The combination, with the upper and lower portions of a lamppost, of a signal-box frame secured between said portions, and having a rear plate provided with a hollow rib and illuminating and signaling wires, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
